Could you improve the bank or maybe "guild" vendor" in my guild's dimension/house?

So, I was wondering if there's any plans in the works to allow us to set up guild tabs in a way we can "price" out items for withdrawal? An example would be: A guildie withdraws several vials and, in doing so, pays a preset amount to the guild bank.

An alternative to this would be a guild vendor that we could restock. Maybe, by default, said vendor would sell water and other commonly desired items too.

That's... actually a really cool idea. Make the prices based on ranks, and have a separate tab for the available merchandise, in addition to common drinks, banners, silver relics, and maybe crafting materials, though that might be pushing it.
